Mean: Average of the numbers in a set of data.
The mean of a data set is equal to the sum of the set of numbers divided by how many numbers are in the set. If we want to find the mean of the data set shown here, let's begin by adding the numbers.
35 + 40 + 45 + 50 + 55 + 60 + 65 = 350
Now, this will be divided by how many numbers are in the set which is 7.
350 ÷ 7 = 50.
Therefore, the mean of the set of data shown here is 29.2.

Answer:
3
Step-by-step explanation:
2 + 2 = 4
4 - 1 = 3
Answer:
infinite
Step-by-step explanation:
infinite
but solving for it we can get
3x + 8 = 3x + 8 (divided both sides by 2)
3x = 3x (subtracted 8)
x = x
1 = 1
therefore, for all values of x, the equation will be true so there are
